This chapter describes the Cisco Unified Communications IM and Presence (IM&P) architecture and design. Native presence in Cisco Unified Communications Manager (CUCM) is presented and the different Cisco Unified Communications IM&P approaches are described. Cisco Unified Communications IM&P can be configured to peer with another Cisco Unified Communications IM&P cluster in the same domain or can be federated with Cisco Unified Communications IM&P clusters in a different domain.

NOTE

The previous name of IM&P was Cisco Unified Presence Server (CUPS) in prior versions of Cisco UC.

CUCM Presence Introduction

CUCM offers very limited native presence functionality on IP phones. Although a Cisco Unified Communications IM&P server is not required in this simple example, only these native presence features of the CUCM are available:

CUCM speed-dial presence: CUCM administratively supports the ability for a speed dial to have presence capabilities via a BLF speed dial. BLF speed dials work as both a speed dial and a presence indicator.
